Are Antifreeze and Coolant the Same Thing?

With summer temperatures finally here, you should make sure your engine isn’t overheating. If you let it get too hot, it can cause long-term engine damage and cause a major breakdown. The best way to keep your motor at a stable temperature is by maintaining your vehicle’s cooling system. To be specific, you should ensure your car has enough coolant fluid or antifreeze.

Coolant Versus Antifreeze

You may hear these two terms thrown around interchangeably. Though they are essentially the same thing, there are technical differences. Coolant is the fluid that flows throughout your engine to prevent it from overheating. It is a mixture of water and antifreeze. Antifreeze is a concentrated chemical that helps lower the freezing point of water. When combined with water, it becomes a coolant.


You can buy premixed coolant or an antifreeze concentrate to mix yourself. Over time, you will need to top off your vehicle’s coolant mixture. Furthermore, you may need to flush it when the system gets contaminated or the fluid gets dirty.
